Mechanism for selectively operating and locking a pivotable window

In combination with a pivotable window adapted to be pivotally attached to a window frame so as to pivot between a window open configuration and a window closed configuration about a window pivotal axis, a mechanism for selectively operating and locking said pivotable window, said mechanism including

• an actuating rod, said actuating rod having an elongated configuration defining a rod first end, a rod second end and a rod longitudinal axis;
• a rod mounting means for slidably mounting said actuating rod on said window frame so as to allow said actuating rod to slide relative to said window frame along said rod longitudinal axis;
• a guiding arm, said guiding arm defining a guiding arm first end and a guiding arm second end;
• a guiding arm-to-window frame attachment means extending between said guiding arm and said window frame for pivotally attaching said guiding arm adjacent said guiding arm first end to said window frame adjacent said actuating rod, said guiding arm-to-window frame attachment means allowing said guiding arm to pivot relative to said window frame about a guiding arm pivotal axis;
• an actuating arm, said actuating arm defining an actuating arm first end, an actuating arm second end and an actuating arm longitudinal axis;
• an actuating arm-to-actuating rod attachment means extending between said actuating arm and said actuating rod for pivotally attaching said actuating arm adjacent said actuating arm first end to said actuating rod, said actuating arm-to-actuating rod attachment means allowing said actuating arm to pivot relative to said actuating rod about an actuating arm pivotal axis
• an actuating arm-to-window attachment means extending from said actuating arm adjacent said actuating arm second end for attaching said actuating arm to said window;
• a linking means extending between said guiding and actuating arms for linking said guiding arm adjacent said guiding arm second end to said actuating arm intermediate said actuating arm first and second ends, said linking means being configured so as to selectively allow and prevent pivotal movement between said guiding and actuating arms about a linking pivotal axis depending upon the distance between said guiding arm-to-window frame attachment means and said actuating arm-to-actuating rod attachment means;
• whereby
• slidable movement of said actuating rod relative to said window frame along said rod longitudinal axis in a rod first direction causes the distance between said guiding arm-to-window frame attachment means and said actuating arm-to-actuating rod attachment means to decrease causing said linking means to assume an unlocked configuration and eventually causing said actuating arm to push said window towards said window open configuration;
• slidable movement of said actuating rod relative to said window frame along said rod longitudinal axis in a rod second direction opposite to said rod first direction causes the distance between said guiding arm-to-window frame attachment means and said actuating arm-to-actuating rod attachment means to increase causing said actuating arm to pull said window towards said window closed configuration and eventually causing said linking means to assume a locked configuration.

A mechanism for selectively operating and locking a pivotable window, said window being pivotally attached to a window frame so as to pivot between a window open configuration and a window closed configuration about a window pivotal axis, said mechanism comprising:

• an actuating rod, said actuating rod having an elongated configuration defining a rod first end, a rod second end and a rod longitudinal axis;
• a rod mounting means for slidably mounting said actuating rod on said window frame so as to allow said actuating rod to slide relative to said window frame along said rod longitudinal axis;
• a guiding arm, said guiding arm defining a guiding arm first end and a guiding arm second end;
• a guiding arm-to-window frame attachment means extending between said guiding arm and said window frame for pivotally attaching said guiding arm adjacent said guiding arm first end to said window frame adjacent said actuating rod, said guiding arm-to-window frame attachment means allowing said guiding arm to pivot relative to said window frame about a guiding arm pivotal axis;
• an actuating arm, said actuating arm defining an actuating arm first end, an actuating arm second end and an actuating arm longitudinal axis;
• an actuating arm-to-actuating rod attachment means extending between said actuating arm and said actuating rod for pivotally attaching said actuating arm adjacent said actuating arm first end to said actuating rod, said actuating arm-to-actuating rod attachment means allowing said actuating arm to pivot relative to said actuating rod about an actuating arm pivotal axis
• an actuating arm-to-window attachment means extending from said actuating arm adjacent said actuating arm second end for attaching said actuating arm to said window;
• a linking means extending between said guiding and actuating arms for linking said guiding arm adjacent said guiding arm second end to said actuating arm intermediate said actuating arm first and second ends, said linking means being configured so as to selectively allow and prevent pivotal movement between said guiding and actuating arms about a linking pivotal axis depending upon the distance between said guiding arm-to-window frame attachment means and said actuating arm-to-actuating rod attachment means;
• said linking means including a linking slot formed in said actuating arm and a linking pin extending from said guiding arm and inserted in said linking slot, said linking slot defining a linking slot pivotal section allowing relative pivotal movement between said actuating and linking arms, said linking slot also defining an integrally extending linking slot locking section preventing relative pivotal movement between said actuating and linking arms;
• said linking slot pivotal section allowing pivotal movement of said linking pin thereinto;
• said linking slot locking section being narrower then said linking slot pivotal section and having a generally rectilinear configuration defining a slot longitudinal axis;
• whereby
• slidable movement of said actuating rod relative to said window frame along said rod longitudinal axis in a rod first direction causes the distance between said guiding arm-to-window frame attachment means and said actuating arm-to-actuating rod attachment means to decrease causing said linking means to assume an unlocked configuration and eventually causing said actuating arm to push said window towards said window open configuration;
• slidable movement of said actuating rod relative to said window frame along said rod longitudinal axis in a rod second direction opposite to said rod first direction causes the distance between said guiding arm-to-window frame attachment means and said actuating arm-to-actuating rod attachment means to increase causing said actuating and guiding arms to pivot about said linking pin located in said linking slot pivotal section until said window is in said window closed configuration, continued slidable movement of said actuating rod relative to said window frame along said rod longitudinal axis in said rod second direction causes said linking pin to slide into said linking slot locking section preventing relative pivotal movement between said guiding and actuating arms until slidable movement of said actuating rod relative to said window frame is reversed and said linking pin reaches said linking slot pivotal section.
